Why does my DeLonghi HX65L22 Heater display 'H.t' and switch off?

If your DeLonghi Heater displays 'H.t' and switches off, it indicates that the internal temperature is too high. To resolve this: * Unplug the heater from the power outlet. * Allow the appliance to cool down. * Ensure that the air intake and outlet grilles are not blocked and that the heater is properly positioned, maintaining the minimum distances from walls or other objects. Refer to Fig. 2 in the manual for guidance. * After a few minutes, plug the heater back in. The unit should return to standby mode.
